Cornett heating is the best. They came quickly and diagnosed the problem within 15 mins. Ordered the part 25 mins later and picked up the part and back at my house in little over an hour and all of this on a Friday afternoon before the snowstorm of the decade!!! Thanks to the 2 very nice young men that restored our heat so quickly and Danny for getting the part ordered so fast!! So appreciate the great service we receive from this company!!

New customer. I was unable to contact our original installation company so I called Cornett from a Facebook post. Left a message at 9a, was called back and scheduled and fixed by 2p. Danny is a gem. So polite and truly wanted me to learn what happened and why the part needed replaced. Beyond trustworthy. This company is top notch and completely deserves 10 stars!
